ABSTRACT:
A radial power combining scheme is provided for combining a plurality of field-effect transistor-based amplifiers to form an amplifier circuit. The amplifier circuit includes input terminals for receiving high frequency power signals. A radial line power combiner/divider is provided for dividing the input signal amongst a plurality of amplifiers. The radial line power combiner/divider is further adapted to receive and combine the amplified signals which are then provided to an output. The circuit advantageously utilizes a plurality of three-port circulators for transmitting the signals within the circuit.
